Self-pollination occurs in flowers where the stamen and carpel mature at the same time, and are positioned so that the pollen can land on the flower's stigma. This method of pollination does not require an investment from the plant to provide nectar and pollen as food for pollinators.

Which flowers are self-pollinating?

Examples. Arum lilies, tridax (part of the daisy family) and some orchids are self-pollinating flowers. Dates, box-elder and buffalo berry are self-pollinating flowering trees. There are quite a few vegetables that self-pollinate, such as tomatoes, okra, peas, snap peas, soybeans and lima beans.

Can a flower self pollinate only if it contains?

When the pollen is transferred from the anthers of a flower to the stigma of the same flower, it is called as self- pollination. This form of pollination is common in hermaphrodite or dioecious plants which contain both male and female sexual parts on the same flower.
